Suppose that Verania and Josimar are roommates that need to complete some household chores. Vacuuming and washing dishes need to be done. They know from the last time they did these chores that it takes Verania 2 hours to vacuum and 1 hour to wash dishes. It takes Josimar 3 hours to vacuum and 2 hours to wash dishes. Josimar says it does not matter which task each of them performs because Verania is faster at both tasks. Josimar’s reasoning a. is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum. b. is correct. Because Verania is faster at both tasks, there is no benefit in each volunteer specializing in one task or the other. c. is wrong. Because Verania has an absolute advantage in both tasks, she should perform both tasks herself. d. is wrong. Because Josimar has a comparative advantage in washing dishes, he should wash dishes, and Verania should vacuum.

Milo is the young, likable, optimistic, and generous son of a prominent public official. He has a master's degree in business and is the business partner of Kent and Lily in an oil drilling and exploration business. Milo also serves as a director on the board of the Corley Savings and Loan Association. While serving on the Corley Board, Milo votes to approve major loans to Kent and Lily without disclosing to the other directors that he is a business partner of Kent and Lily. Milo also personally arranges for a $900,000 line of credit from Corley for an oil drilling venture in which he is a partner with Kent. The drilling venture is unsuccessful and Kent and Lily both default on their loans to Corley, which then causes the S & L to become insolvent. Federal banking officials seize Corley and liquidate its assets to pay creditors and depositors. Because Corley is federally insured, tax money is also used to pay off depositors whose deposits are insured under federal programs. Corley…

After Hurricane Maria, hundreds of nonprofit organizations streamed to Puerto Rico and other Caribbean islands to provide disaster relief. Research has found that coordination between nonprofits during disasters is difficult to maintain—it’s easy for individual nonprofits to fundraise and pursue programming on their own while ignoring other organizations working on the same issues. Additionally, there are incentives to do projects that are cheap and have fast turnaround, since donors respond to the visibility of organizations providing disaster relief.   Consider two nonprofit organizations working in Puerto Rico. Together, they could spend time coordinating their efforts and run a shelter for hurricane victims, providing each organization with 100 utils. Alternatively, they could individually distribute paper towels—a simple, low-cost, fast, and visible project—and receive 5 utils.   This situation can be modeled with the following payoff matrix:     Nonprofit 2       Run Shelter…

Table 8P-4 lists the prices and quantities consumed of three different goods from 2014-2016. [LO 8.2] a. For 20142015, and 2016, determine the amount 4, 20 that a typical consumer pays each year to pur chase the quantities listed in the table. b. Using the amounts you found in part a, calculate the percentage change in the amount the con sumer paid from 2014 14 to 2015 , and from 2015 to 2016. c. Why is it problematic to use your answers to part b as a measure of inflation ? d. Suppose we take 2014 as the base year, which implies that the market basket is fixed at the 2014 consumption levels. Using 2014 consump tion levels, now find the rate of inflation from 2014 to 2015 and from 2015 to 2016. (Hint : First calculate the cost of the 2014 market basket using each year's prices and then find the per centage change in the cost of the basket. ) e. Repeat the exercise from part d, now assuming that the base year is 2015. f. Why were your answers from parts d and e different?
